Assuming all taxes are paid for... I'd take 1 million to buy a house, car, furniture, and all the necessities of life (I wouldn't spend more than $250,000 on a home and land). I'd take another million and split it up among all those close relatives who have helped me throughout the years. Another 2 million would go towards investments (mostly moderate and conservative investments and a small portion to high risks). Then I'd take yet another 2 million and stick it in the bank (several different and secure accounts) or some other form of very conservative manner of bearing interest, and I would live off of approximately $50,000 a year for the rest of my life (40 years).
With a house which is fully owned, etc. living on $50,000 would be quite easy and rather comfortable for me, especially since I'd have the equipment installed to produce my own electricity so I could sell the surplus back to the power company rather than paying them for my power.
I'd split up 1 million across the board to worth while charities who held similar positions for their cause as myself. Then I would, of course, sock away 2 million for my kid. Finally, I would take the remaining 1 million and determine how best to store it away to keep bearing interest, yet allow me to pay my taxes each year.
Or something along those lines...
